• Sequencer LTC2937 up and down sequence issue


    Using Sequencer LTC2937 and programming with the DC1613A.

    The sequencer does not start to sequence up, or is stuck right after it turns on.

    I set some of the voltages to turn on by setting them to seq. position 0 and enable at startup, which works…

  • LTC2937 Power Sequencing with 4 in parallel (24 outputs simultaneously)

    I want to connect 24 voltage supplies for power sequencing. I have selected LTC2937 for the power sequencing and would like to know if I can connect 4 LTC2937 in parallel. Also I would like to know how many maximum LTC2937 can I connect in parallel? Are…

  • LTC2937 ON Pin control circuitry


    I have a question regarding the external control circuitry connected to the ON Pin off the LTC2937. The block diagram in the datasheet shows an internal 10µA current source pulling up the ON Pins potential to VDD (3.3V). The "usual" use case of the…

  • LTC2937 Programming


    We are using DC1613A and DC2347A for LTC2937 Socketed Programming.

    1. Is there a Socketed board can support multiple LTC2937 Programming  at once?


  • LTC2937 Behavior at Power On

    What state are the Enable outputs in at VDD power up of the LTC2937? 

    What happens when VDD is below the under voltage lockout level? 

    Does keeping the ON input low at VDD power up force the Enable outputs to stay low?

    Thanks for your help.

  • RE: LTC2937MP — "Could not add chips"

    Hi KM,

    Given that the GUI was mostly greyed out and the programming failed when trying to determine if the part it was speaking to was an LTC2937, we suspect that this is an addressing issue.  It seems the part may not be at the right address or there…

  • LT3040 shutdown behavior

    Dear All,

    I have a doubt concerning the shutdown behavior of the LT3040.

    On page 21, in the power supply sequencing paragraph the datasheet says:

    If the VIN pin is powered high while LT3040 is in shutdown, the DC current flowing through the internal …
